Sauk County, WI tax sales

County offices

County notes

• •The parcel list with appraised minimums is published in the Notice of Sale PDF on the Treasurer's sealed bid page. A county GIS map shows the same parcels and distinguishes those offered by sealed bid from those available by Offer to Purchase.
• •Between sealed bid rounds, the live inventory is the Offer to Purchase list. Confirm with the Treasurer's office at (608) 355-3275 that a parcel is still available before mailing funds, because the full purchase amount must accompany the offer form.
• •The 2026 round offered seven parcels: single lots in the towns of Freedom, LaValle, Merrimac and Woodland plus a house at 617 8th St in the City of Baraboo. Appraised minimums ran from $4,000 for a Dutch Hollow Lake lot in the Town of Woodland to $117,300 for the Baraboo property.
• •Sauk County issues a tax certificate to itself each September 1 covering parcels still delinquent as of August 31, and may begin in rem foreclosure two years later. That certificate is never sold or assigned to investors, so the only entry point is buying after the county holds title.
• •Budget a separate $30.00 check payable to the Register of Deeds with every sealed bid or Offer to Purchase, on top of the purchase money. Both the sealed bid deposit and an Offer to Purchase must be a bank money order or certified check.
• •An Offer to Purchase requires the full offer amount up front, one separate offer per tax parcel, and a W-9. Approved offers are conveyed by quit claim deed recorded with the Register of Deeds.

Wisconsin rules

Redemption

The redemption right in Wisconsin runs against the county, and it is over before an investor sees the parcel. Issuance of the tax certificate on September 1 starts the clock. Two years later the county may take its deed or start a foreclosure, but the right to redeem does not end on that anniversary: under s. 75.01(1)(b) any person may redeem at any time before the tax deed is presented to the register of deeds and accepted for record, and a redemption before recording makes the deed void as to the land redeemed. On the in rem route under s. 75.521 the county publishes a notice fixing the last day for redemption at least 8 weeks after first publication, and an interested party may instead serve a verified answer within 30 days after that date on the three grounds the section allows. Once the deed is recorded or judgment is entered, redemption is finished. Between the two, at least 6 and not more than 10 months before the redemption period expires, the county treasurer must publish a class 2 notice listing every unredeemed parcel with its amount due and the last day of redemption, which is the public list an investor can watch. Two things can still pull a parcel off a sale list afterward: the minor and incompetency extension in s. 75.03, and the former owner repurchase right in s. 75.35(3).Wisconsin Statutes 75.01 - RedemptionWis.

Deed deposit

Wisconsin fixes no statutory deposit. Section 75.35(2)(am) lets the county board sell its tax-deeded lands in whatever manner and on whatever terms it sets by ordinance or resolution, and s. 75.35(2)(d) lets the board delegate that power to a committee, an officer or a department, or hire licensed real estate brokers on commission. Deposits are county rules, not state law. St. Croix County requires a 10 percent deposit by cashier's check or money order with each sealed bid and rejects personal checks. Counties selling through the statewide online auctioneer instead take payment by certified check or wire transfer under the platform's terms.

Homestead deeds

Owner-occupied homes are treated differently, and the difference can pull a parcel off the list. For single-family, owner-occupied properties the county board must by ordinance give the former owner who lost title, or that person's heirs or beneficiaries, the right to buy the land back before it is sold, on paying the costs and expenses under s. 75.36(3)(a), the property taxes that would have been owed for the year of the purchase, and enough to satisfy any other liens at the time of foreclosure plus the county's repurchase costs. The board may extend the same right to other property types at its option. A sale under that ordinance is exempt from s. 75.69 altogether, so it never reaches a public bid. Counties set their own window. Dane County gives the former owner 60 days from delivery of the treasurer's certified-mail notice. Treat an owner-occupied house on a Wisconsin land sale list as provisional until the repurchase window has closed.Wisconsin Statutes 75.35 - Sale of tax-deeded lands; purchase of adjacent landsWis.

Surplus proceeds

Wisconsin returns the surplus to the former owner, and the county treasurer has to go find them. On taking the tax deed the treasurer must notify the former owner by registered or certified mail, at the mailing address on the tax bill, that the former owner may be entitled to a share of the proceeds of a future sale. When the county sells, the treasurer computes net proceeds by subtracting foreclosure, record-keeping, legal, advertising and title insurance costs, the actual maintenance, board-up, clean-up and demolition costs reasonably needed to sell, real estate agent or broker fees, and all unpaid general property taxes, interest, penalties, special assessments, special charges and special taxes. From the net proceeds the treasurer pays any managed forest withdrawal tax and fee, then the taxing jurisdictions' special assessments and special charges, prorated if the money runs short. Anything still remaining goes to the former owner, less any delinquent taxes, interest and penalties that person owes the county on other property. A payment unclaimed one year after mailing becomes unclaimed funds under s. 59.66(2), and no interest is paid on any of it.Wisconsin Statutes 75.36 - County acquisition and sale of property (net proceeds and the former owner's share)Wis.

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
